Trees of medium size with dark brown thick bark, deeply 
furrowed, spreading limbs and cones at maturity, broken at 
base—belonging to my group of broken-cone pines. The 
leaves persistent near the ends of the stout branchlets, have 
the resin ducts near the epidermis and surrounded by 
strengthening cells—characters pointed out by Dr. Engel- 
mann as distinguishing his group Ponprrosm. The leaf- 
bracts soon reflexed, are 3 of an inch long, lanceolate, acumi- 
nate, subulate, with the scarious margin laciniate: leaves in 
threes (rarely four or five) stout and long, 12 to 16 inches long 
and + of an inch wide, serrulate towards the tip, sheaths 
an inch or more long, light brown, becoming black with age, 
the close-wrapped bracts strongly lanciniate-fringed; male 
flowers (as to the Chirricahui specimens) large, 14 inches 
long, erect or spreading; involucral scales 8, large and firm; 
anthers with large, orbicular, crenulate crests (tardily dehis- 
cent at maturity, leaving basal scales) solitary or in whorls 
of 2 to 6, spreading or slightly declined, ovate or elongated, 
4 to 6 inches long, of few or many developed scales, the apo- 
physes usually not prominently elevated, rarely a few near 
the base (still more rarely all the scales) conical-tuberculate, 
in which case they are tipped with slender prickles, usually 
the low quadrangular apophysis is armed with a stout deltoid, 
erect or spreading, discolored prickle: seeds oval, 4 inch 
long, prominently ridged on the upper side and conspicuously 
brown mottled, wing resembling P. ponderosa.

Chihuahua Mountains, reaching 40 to 60 feet in height with a
